To all whom t may concern.'

Be it known that I, ARTHUR XV. WALKER, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Cooking Stoves and Ranges, of which the following is a specification.

This invention relates mainly to convertible cooking stoves and ranges, that is to say, to stoves and ranges of that type in which provision is made for supplying heat to the oven either from its exterior, asJ by means of solid fuel burned in the fire box, or internally by means of gas or liquid fuel burnedfwithin the oven or at or adjacent to its bottom, and is particularly intended to provide a simple and practical stove of the character above referred to which be readily arranged for use with either form of fuel without the addition to the stove of various attachments required heretofore. Certain features of the invention, however, are of wider applicability and may be'embodied in a non-convertible cooking stove or range.

In the accompanying drawings z-Figure l is a vertical longitudinal section through the body portion of a convertible stove embodying my improvements, as preferably constructed; Fig. 2 is a front elevation on a larger scale, showing the oven door and adjacent parts with the door in closed position; Fig. 3 is a section on the line 3 3 in Fig. 2; Fig. 4 is a vertical longitudinal sec- 4tion through the oven showing a slightly modied arrangement of the parts contained therein; Fig. 5 is a view correspond-4 ing to the left hand end of Fig. 4 but showing the parts in a diderent position; Fig.l 6 is a section on the line 6 6 in Fig. 4,

land 10 are sectional views similar to Figs.

4, 5 and 6, and further illustrating the construction shown in Figs. l and 2; Figs. 1l and 12 are detail views of parts hereinafter described. Fig. 13 is a detail view in horizontal section on the line 13-13 in Fig. 2,

with certain parts omitted; and Fig. V14 is a view similar to Fig. 4, illustrating a modification.

rThe stove illustrated in the drawings lcoinprisesa body7 A2 having the usual Ylire-1 box 3, an oven 4, and flues 5 located between the oven 4 and the surrounding body 2, the door of the oven being shown at 6. TVithin the oven are located two partitions 7, 7, which are so arranged that they may be moved at will into the position shown in Fig. 4, in which they occupy an upright position at suitable distances from the sides of the oven to provide flues between the latter and the partitions when the oven is to be heated by gas, or moved out of the way when it is desired to heat the oven by means of fuel burned in the fire box 3. This movement of the partitions 7 may be provided for in various ways, but preferably, as in the particular construction illustrated, each partition is provided at suitable points with pivoted links 8 so proportioned and arranged as to permit the partitions to be moved upward and backward against the re spective sides of the oven as shown in Fig. 5, where they may be locked by suitable means such as is hereinafter described.

In addition to the partitions 7 the oven 4 is provided with one or more bottom burners suitable for the fuel intended to be used, each burner being so larranged that it may be moved into suitable position for use in burning the fuel employed, or moved out of the way when the oven is to be heated by means of coal or other fuel burned in the fire box. Various forms of burner may be utilized and the desired movement of the same may be provided for in any suitable manner, but according to the construction illustrated in the drawings two similar gas burners are employed, each burner consisting of a pipe 9 extending from the front to the back of the oven and having perforations 10 or other openings for the escape of the mixed gas and air from the pipe when the burner is in use. Each of these pipes 9 is pivotally mounted within the oven in such mannerthat the perforated portion of the pipe may be caused to rest upon the floor ofthe oven or swung upward toward one side of the same, as shown in Figs. 4 and 5, respectively, to which end each burner (shown in detail in Fig. 12) is provided at one end with an olfset pivot 11 adapted to enter a suitable recess in the back wall of the oven, while its other end portion is bent outward in line with the pivot 11, as at 12, and located within a perforation in the front wall of the oven adjacent to one of the lower front corners thereof, where its outer the stove and provided with the usual stop cock 14, for regulating the supply of gas.

Provision is also made for supplying airy to the burner in connection with the gas which enters it, as by means of openings 15 in the outer end of the burner, adjacent to the discharge end of the supply pipe 13, which openings may be regulated in size by an adjustable damper 16 in the usual manner.

In the construction shown in Figs. 4, 5, 6 and 7, the partitions and burners are each movable independently of the others, but in order to simplify the operation of arranging the parts for use in connection with either fuel, I prefer to connect the partitions and burners in such manner that the operation of one will operate the other. Such an arrangement is illustrated in Figs. 1, 2, 3, 8 and 9, in which the lower end of each partition 7 is pivoted to the adjacent burner in such manner that the burner takes the place of the lowermost links 8 shown in Fig. 4t. Tith this arrangement, when either burner is swung upward toward the corresponding side of the oven the corresponding partition is lifted with it, and in order to keep the oven as clear as possible from obstructing parts the side walls thereof are preferably offset outwardly at their lower portions, as shown at 17, toreceive the adj a cent burners, and the lower portions of the partitions 7 are similarly oifset to t between the burners and the off-set portions of the oven walls, so that when the burners and partitions are moved upward they will lie flat against the side walls of the oven and will not occupy any substantial portion of its interior, as shown in Fig. 9. The burners may be looked in this position by means of pivoted hooks 18 each arranged to engage a pin 1S) carried by the corresponding burner, and the partitions will evidently be held in their uppermost position by the burners whether the partitions and burners are connected to each other or not, in case the offset arrangement above described is employed.

As thus constructed, the oven is arranged for use with coal as a fuel by moving the burners and partitions upward and backward against the sides of the oven and se curing them in such position as already described, in which position of said parts the 'interior of the oven is substantially unobstructed by the contained parts and has its full capacity to receive its intended contents, the partitions 7 and 7 being preferably provided with a suitable number of ledges 20 adapted vto support one or more shelves 2]., on whichvarious articles may be placed. Whenit is. desired to ,heat the oven by ineans of gas the burners and partitions are moved into the position shown in Figs. 1 and l and a false-bottoni 22 is in-V serted into the oven above the burners, thus providing an interior oven of slightly reduced capacity, which may be heated by admitting gas to the pipes 9 and lighting the gas beneath the false bottom 22. The spaces left between the partitions 7 or 7 and the side walls of the oven, `in connection with openings 23 formed in the lower edges of the partitions below the level of the false bottom 22, provide lines through which the hot gases resulting from the combustion pass upward between the partitions and the side walls of the oven, and these products of combustion are preferably admitted to the interior oven through openings 2e formed in the partitions between the ledges 20, so that the hot gases thus come in direct contact with the articles to be cooked, as is customary in gas-heated ovens. In order to limit the movement of these hot gases to the path just indicated, the oven door is provided, wherever necessary,I with inwardly-projecting ledges or flanges 25 arranged in alinement with the lowered partitions 7 or 7 and adapted to come into close proximity to the front edges ofthe same when the oven door is closed, (seeV Fig. 13) so that the gases are prevented from passing around the front edges of the partitions between the same and the door.

Provision is made for the escape of the products of combustion from the oven by providing the latter with 'one or more suitable outlet openings, such as 26, and in the drawings I have shown an arrangement for automatically opening these outlet openings when the parts vare arranged for the use of gas as a fuel and for automatically closing said openings at other times. This is accomplished by means of dampers 27, one for each opening, each damper being mounted on one of the walls of the oven and connected at one end with one of the movable parts, such as the adjacent partition 7 or 7 in such manner that when said movable parts are held against the side walls of the oven the dampers 27 are located directly in front of and close to the openings 26, while when said movable parts are in position for the use of gas Vthe dampers are moved away from the openings, as shown in Fig. 1, for example. In the particular constructions illustrated, each Vdamper 27 is pivotally mounted on the rear wall of the oven and provided at one end with a slot 28 which receives a pin 29 fixed to the corresponding partition 7 or 7 Provision may also be made, if desired, for admitting air to the interior of the gas oven,'as by providing the oven door 6 with one or more dampers 30, each hinged thereto in such manner as to automatically ,close an opening rest upon the ledges.

31 formed in the door when the false bottom 22 is removed and the partitions and burners are folded up against the side walls of the oven. When said parts are in position for use, however, one of them, such as the pipe 9, is located in position to be engaged by the end ofl an arm 32 carried by the corresponding damper when the oven door is closed, thus causing said damper to swing outward and open the aperture beneath it, as shown in Fig. 3.

The ledges 20 on the partitions 7 and 7 serve to support shelves within the oven when gas is burned, just as they serve the same purpose when said partitions are folded against the side walls of the oven, except 'that in the latter case the shelves must be wider than in the former case in order to Therefore, in order to avoid the employment of two sets of shelves, I forni each shelf 21 of such a size that in one dimension it is Wide enough to rest upon the ledges 20 when the partitions are moved upward and backward, while its other dimension is such that it will rest upon said ledges when the partitions are in their j innermost position, so that each shelf may be used in connection with either arrangement of the parts contained within the oven.

Instead of employing two internal partitions for the purpose above described, one such partition may be utilized in connection with any suitable number and arrangement of burners, in which case the ledges on said partition will coperate with the opposite ledges such as are commonly provided on the side walls of the oven in non-convertible stoves. Such a construction is illustrated in Fig. 14, which shows an oven containing at its left hand side a movable partition and burner like those already described, while the right hand side of the oven is merely provided with ledges 20 so arranged as to coperate with the ledges 20 on the movable partition in either position of the latter for the purpose of holding shelves. That par-V tition which is nearest the fire box 8 is also capable of serving a useful purpose independently of any gas burner, in that it may be used when moved inward or away from the side wall of the oven as a baking shieldV for securing uniformity in the heating of the oven by means of the fuel in the fire box, this feature of my invention being applicable to non-convertible cooking stoves and ranges. The movable partitions or either of them may also be used in connection with a fixed broiling burner, such a burner being indicated at 33 in Fig. 4, or with various other forms and arrangements of burners, and the features and ldetails of the construction illustrated and described maybe widely modied in other particulars without departing from the substance of mv inyentipn, as lwill be` evident.
